The 4 indicates that this is a 4 speed transmission, with it being an automatic transmission in this case. You'll need the appropriate transmission rebuild kit for your 4L60E. While a number of differences exist, the easiest to recognize externally is the fact that the bell-housing is removable for the Late 4L60E transmissions. The placement of this tab is absolutely critical. An evolution of the popular 700R4, the 4L60E, is a popular swap transmission.
In order for it to work better and more effectively, it has to have high quality parts inside. One of the goals for this project was to use as many factory components as possible, and most of the build came straight from the Chevrolet Performance Parts catalog. These mechanical speedometer tailshafts are for the 4L60E and 4L65E transmissions. The Tri-Five Chevy works well with the Corvette accessory drive, which was taken directly from the Chevrolet Performance catalog. The next major change was a six-bolt extension housing in 1993, compared to the original four-bolt. Most higher end rebuild kits will include a new shift kit as well.
Are there low-profile pans for the 4l80e? The 4L60E uses computer control to shift. A jack and jack stands or a set of ramps are necessary to get your vehicle up high enough off the ground so you can get underneath it. Alternatively, you can use the flex plate and the from the 4l80e transmission. Length and volume of the cooling circuit will vary and will require an additional amount. However, you can also find both new and used transmissions and parts online and one of the places to check for these are on Amazon. As with the previous model I reviewed, when you convert from an older vehicle, consider adding a transmission controller, crankshaft spacer, special cross-member, driveshaft changes and other modifications which are not included with this package. This kit was designed to adapt the late model 4L60E hex bolt pattern to any 700R adapter that Advance Adapters manufactures.
As engine and transmission mounts differ, each shifter must be ordered individually. An automatic transmission shift kit is only needed if you want the gears to shift sooner, but it can also reduce transmission wear by reducing or eliminating shift overlap. To adapt these shifters to match the stock location, a Hurst Blackjack shifter can reposition the shifter to the ideal location. Just with these number, you can probably calculate that there is a big difference in size and weight between these transmissions. If you would like to read more about the evolution of the 4L60E over the years, check this article out: Conclusion: 4L60 vs.
There may be parts of the rebuild process that you are not very familiar with, or you may be new to this particular type of transmission. The T56 needs a different tailhousing for a mechanical speedometer. Using a torque wrench and a tightening in a star like pattern, torque the pan bolts to 98 — 108 lb-ft. Both will result in a transmission fluid leak. Additionally, the removable bell-housing is also another distinguishing feature. Later transmissions were upgraded as 4L65 and 4L70 for use in heavy-duty trucks. Photo Courtesy General Motors Flexplate The 6.
You can the transmission wiring harness swap kit here from Amazon: Dipstick The dipstick is different on the 4l80e transmission and you have to consider this when doing your swap. Start out by getting your vehicle up in the air, using your jack and jack stands or your ramps. The vehicle technology is achieving ever so high progress. The rest of the exhaust was made from 2. If you have a 4L60e you can probably also go to a junkyard and find parts for your transmission, depending on where you live.
In 1996, a bolt-on was phased in along with a six-bolt tailhousing for S-10 Trucks and S-10 Blazers and beginning in 1998 for all other applications. The 4 gears available in this transmission are 3. An Iowa native, Smith served a variety of roles at Car Craft before moving to the senior editor role at Hot Rod and Chevy High Performance, and ultimately returning to Car Craft. Two-wheel-drive versions have tail-housings and typically a longer output shafts than four-wheel-drive versions, which have various adapter assemblies and a shorter output shaft. Wiring Harness There is a lot of difference when it comes to the wirings and sensors for the transmissions. The last bellhousing type is the special Corvette adapter.
One of the most common problems with this transmission is losing the ability to use the reverse gear, commonly caused by debris buildup. A heavy flywheel holds more inertia for smoother shifts and easier street driving. Third gear is 1:1, with overdrive again engaged to create Fourth. If I have missed something or if you have any other questions, you are welcome to ask your questions down below and I will answer them as soon as possible. Do not over tighten the bolts as this will cause the pan gasket to get squeezed out, or the pan to warp. As you disassemble your transmission, make note of any obvious wear to parts that may need replacing. My reason for leaving you with this technical information is a way of making a strong impression on why it is so easy to deal with a specialty with the proper identification information and practical usable experience.
Care must be taken due to different torque converter bolt patterns and length for each of the bellhousings. This transmission can still be found in light-duty van applications as well as in the overseas market in the Holden Commodore. The previous versions featured a four-bolt square bolt pattern at the adapter or tail-housing. A cable then connects to the other side. Though there are many little fine intricacies that are beyond the scope of this article. Many of the stand-alone controllers will indicate speed, but this requires using their display.
The chart below is a simple description of these Chevy transmissions using both the more common designations on the left and the factory technical designation on the right. What the engine is capable of doing is to support a 5. The kit also includes a Reman Pump with a new rotor vane slide, a corvette servo, a 0. It was the workhorse of the at the turn of the century. The stator and input shaft also had some variations. You can see the pictures of the gasket in the specification above.
